This paper describes progress made by the NPL, NMISA and RISE collaboration on developing the "Next Generation"Kibble balance. Delays to the availability of the full size balances have concentrated work on the smaller Demonstration balances, which were developed by NPL to provide publicity for the redefinition of the kilogram. The Demonstration balances now work in an almost identical way to the planned, full size "Next Generation"Kibble balance, using the same software and much of the same electronics. This has allowed all three groups to solve problems and make advances that will speed up the work on the "Next Generation"Kibble balance. It will also allow the investigation of wider applications of Kibble balance technology using the software and compact electronics which has been developed.
